Two species of false click beetles, Microrhagus pyrenaeus Bonvouloir, 1872 and Hylis simonae (Olexa, 1970), previously considered endemic to Central and South Europe, are reported from Russia for the first time based on specimens collected in Krasnodar Territory.
Catalog of the type specimens (holotypes, syntypes) of species of the family Mydidae (Diptera) described by A.P. Semenov-Tian-Shanskij and I.A. Porchinsky which are stored in the collection of the Zoological Institute of the Russian Academy of Sciences in St. Petersburg is presented. Photographs of the specimens and their labels are given.
The taxonomic status of Bryophila dolopis Hampson, 1908 is discussed. The validity of the species is substantiated based on the morphological and molecular data. Description and diagnosis of this species are given. The distribution ranges of two closely related species, B. dolopis and B. felina (Eversmann, 1852), are described: B. dolopis is distributed in Southern Kazakhstan, Turkmenistan, Kyrgyzstan, Tajikistan, Pakistan, Iran, and China; B. felina is distributed in Central, South, and East Europe, in the Caucasus and Transcaucasia, in the western part of Asia Minor, and in Lebanon.
Oulema duftschmidi (Redtenbacher, 1874), Phyllotreta astrachanica Lopatin, 1977, and Ph. procera (Redtenbacher, 1849) are recorded for the first time for Uzbekistan; Longitarsus stragulatus dichrous Khnzorian, 1962 is recorded for the first time for Tajikistan. The geographic distribution of Acolastus pallidus (Lopatin, 1956) and Aphilenia ornata Reitter, 1889 is clarified. For all the taxa considered, images of the adult habitus and male genitalia (for some of them) are given.
Two species of the tribe Idiocerini (Cicadellidae, Eurymelinae), Theronopus spicatus (Webb, 1976) and Kopamerra truncata (Webb, 1975), are recorded for the first time from Sudan. The species were collected in Kassala Province of Eastern Sudan.
An invasive Nearctic weevil, Stenopelmus rufinasus Gyll., introduced on all continents of the Eastern Hemisphere, is reported for the first time from Russia where it was found on the Sea of Azov and the Black Sea coasts.
A new species Diplocolenus (Verdanulus) stepposus sp. n. with a Ponto-Kazakhstanian steppe distribution is described. The species is monophagous on the Volga fescue Festuca valesiaca (Poaceae). Arguments in support of the distinctness of the subgenus Verdanulus are given. Some morphological transformations of the male genitalia in the genus Diplocolenus as a whole are discussed. It is hypothesized that the subgenera Diplocolenus s. str. and Verdanus Oman spread into the Nearctic independently and at different times.
The assemblage of hymenopteran parasitoids associated with the invasive lime leaf miner Phyllonorycter issikii (Lepidoptera, Gracillariidae), developing on the lime Tilia cordata, was studied in Kurgan Province (Lake Medvezhye) and in the cities of Tobolsk, Omsk, and Novosibirsk during 2018–2019. Twenty-one species of parasitoids of Ph. issikii were recorded: Pteromalus sp. (Pteromalidae), Cirrospilus diallus, Elachertus sp., Hyssopus geniculatus, H. nigritulus, Pnigalio mediterraneus, Pnigalio sp., Sympiesis dolichogaster, S. gordius, S. sericeicornis, Chrysocharis laomedon, Ch. pentheus, Ch. pubicornis, Ch. viridis, Chrysocharis sp., Neochrysocharis formosus, Minotetrastichus frontalis (Eulophidae), Colastes braconius, Apanteles sp., Pholetesor circumscriptus, and Cotesia sp. (Braconidae). Chrysocharis viridis was recorded as a parasitoid of lime leaf miner for the first time. The role of parasitoids in the miner mortality was negligible, the mortality rate ranging from 1.9 ± 0.4% (Novosibirsk) to 23.7 ± 3.3% (Omsk).
Consortive associations of insects and springtails with the Asian globeflower Trollius asiaticus L. (Ranunculaceae) were studied in the field and in the Bioresource Scientific Collection of the Central Siberian Botanical Garden (Siberian Branch, Russian Academy of Science; USU no. 440534) in 2017–2021. A total of 106 arthropod species were recorded, which were classified into the following groups: (1) anthophiles, (2) herbivores (phyllophages and carpophages), (3) detritophages, and (4) entomophages. Their diversity was the highest during plant blossoming, when the consortium was dominated by anthophilous forms, including pollinators and non-pollinating nectar consumers. The seeds were damaged by fly larvae of the genus Chiastocheta (Anthomyiidae) and by numerous true bugs. The phyllophages did not cause any considerable damage to the Asian globeflower.
The purpose of this study was to test the ability of the parsnip Pastinaca sativa, a furanocoumarin producing plant, to attract the same insect species as Sosnowsky’s hogweed Heracleum sosnowskyi, the most dangerous weed widespread in Russia. A total of 46 species of pollinating insects from the orders Hymenoptera (3 species), Hemiptera (2), Coleoptera (10), and Diptera (31 species) were recorded on P. sativa. Most of the species in the latter order belonged to the families Tachinidae (6 species), Anthomyiidae (6), Calliphoridae (4), and Syrphidae (4 species). About a half of the insect species pollinating P. sativa were also found on other umbellifers, including the native plants Anthriscus sylvestris, Aegopodium podagraria, Angelica sylvestris, the cultivated species Anethum graveolens, Petroselinum crispum, Carum carvi, Coriandrum sativum, Levisticum officinale, and the invasive weed H. sosnowskyi. The pollinators did not reveal any distinct preference for the corolla color (yellow or white), the plant height (from 30 cm to 2 m) or the umbel diameter (from 8 to 30 cm). All the recorded insects can be divided into the following groups: those found on P. sativa and on wild umbellifers (6 species); those found on P. sativa and cultivated umbellifers (4 species); those found on P. sativa and Heracleum sosnowskyi (4 species); those found on many species of Apiaceae (10 species); those recorded only on P. sativa (24 species).
